with the sal tutorials.

(make-cycle (list (make-heap '(a b c))
(make-heap '(d e f)))))
(next pat 50)
=> (b c a f e d b a c e f d b c a e d f b c a f e d a c b d f e a c b
e d f a b c d f e b c a d f e b a)
You are getting confused about creating patterns and reading patterns
1 first construct a pattern with the (make-XXX ...) function (where
XXX is some pattern name)
2 once you have a pattern (that might contain other patterns) you read
items from it using (next ...)
